Frequently Asked Questions (FAQ)
Q1: What makes the CIR90 DTH Hammer suitable for low air pressure?
A: The CIR90 is specifically designed with a patented steel valve system that allows it to maintain high impact energy even when operating at lower air pressures between 5-10 Bar.
Q2: How much does the patented steel valve design improve performance?
A: The unique steel valve design increases the overall work efficiency of the hammer by at least 20% compared to non-patented designs.
Q3: What are the primary applications for the CIR series hammers?
A: These hammers are widely used for mining, quarrying, water well drilling, road construction, anchoring, and slope protection projects.
Q4: What size drill bits are compatible with the CIR90?
A: The CIR90 hammer is designed to work with drill bit diameters ranging from 90mm to 120mm.
Q5: How is the durability of the internal components ensured?
A: All critical internal components, including the piston and valve, undergo strict heat treatment processes to maximize wear resistance and tool life.
Q6: Is the wear sleeve reversible in the CIR series?
A: No, the CIR series hammers utilize a non-reversible wear sleeve design as part of their high-performance internal configuration.
